Liquid capillary scintillation detectors

Liquid-in-capillary detectors for tracking applications in high-energy physics experiments are discussed. The detectors consist of glass capillaries of low refractive indexfilled with liquids of sufficiently high refractive indexto produce an efficient waveguides. The preparation of scintillating core liquids from the solvent 1-phenylnaphthalene and single solutes of selected fluorescent dyes is described. >
